AWS Graviton is a family of 64-bit ARM-based CPUs designed by the Amazon Web Services (AWS) subsidiary Annapurna Labs. The processor family is distinguished by its lower energy use relative to x86-64, static clock rates, and omission of simultaneous multithreading. It was designed to be tightly integrated with AWS servers and datacenters, and is not sold outside Amazon.[1]
In 2018, AWS released the first version of Graviton suitable for open-source and non-performance-critical scripting workloads as part of its A1 instance family.[2] The second generation, AWS Graviton2, was announced in December 2019 as the first of its sixth generation instances, with AWS promising 40% improved price/performance over fifth generation Intel and AMD instances[3] and an average of 72% reduction in power consumption.[4] In May 2022, AWS made available Graviton3 processors as part of its seventh generation EC2 instances, offering a further 25% better compute performance over Graviton2.[5]
